Short period measurement of feed intake in the laying hen for a genetic study of feed efficiency

Short period measurement of feed intake in the laying hen for a genetic study of feed efficiency

Annales de Genetique et de Selection Animale 7(3): 331-334

Correlations were obtained within several experimental groups between the feed consumption of laying hens measured over a long period (3 mo.) and that measured over a shorter period (16 days), after correction for body weight and egg mass produced during the whole period. The observed values for these correlations suggest that corrected feed consumption estimated over about 2 wk can be a sufficient selection criterion for feed conversion efficiency.
